RTBBER HEEL.

Application filed January 25, 1910.

To all whom t may concern.:

Be it known that I, FRANKLIN `W. Kanarien, a citizen of the UnitedStates, residing at Carlstadt, in Dthe cour ty of Bergen and State ofNew Jersey, have invented new and useful Rubber Heels, of which thefollowing is a specification.

This invention relates to rubber heels.

In devices of this kind as usually constructed, a metal washer or thelike is embedded within the body of the heel. It is found in practicehowever that this washer frequently cuts through the rubber coverinfvand destroys the use of the rubber heel.

2Tne of the objects of the present invention is to provide a form ofrubber heel in which the metallic wa her is dispensed with, withoutsacrificing 4he durability of the article.

Further objects of the invention are generally to improve and simplifythe construction of rubber heels as well as to decrease the expenseattending their manufacture and to render them more durable in use.

With the foregoing and other objects in view which will appear .as the'description proceeds, the invention resides in the combinationandarrangementof parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiments of invention hereir. disclosed can be made within the scopeoi. the following claim without departing from the spirit of theinvention or sacrificing any of its advantages.

ln the accompanying drawings forming part of this specification, Figure1 is a perspective view partly in irregular section of a heel constiucted in accordance with the present invention. -Fig. 2 is a transversevertical section on the line 2-2 of Fig. 1. Fig. 3 is a verticallongitudinal section on Fig. f1 is a plan view of a modifiedconstruction. Fig. 5

is a sectior. of the line 5 5 of Fig. 4. Fig.

6 is a perspective view of the modied form of insert.

'i Like reference numerals indicate corre- The heel of the presentinvention consists of a lresilient rubber body portion with a hardrubber insert or core completely em- Speccaton of Letters yat-ent.

bedded therein, the insert being nearer to the upper sides'of the heelthan to the lower sides thereof, said heel being likewise pro* videdwith nail holes which preferably eX- tend through the outer or thickerportion of the resilient rubber body and terminate at the outer edge ofthe hard rubber insert.

Referring to the drawings, the reference numeral 1 indicates the bodyportion of the heel, said body portion being preferably formed ofresilient rubber and having completely embedded therein an insert orreinforcement 2 which is formed preferably of hard rubber.

As shown particularly in Fig. 2 the coat- I ing of resilient rubber isVery much thicker on the outside of the insert 2 than onthe insidethereof. The nail holes 3 by which the heel is secured to the shoeextend through the thick outer portion of the resilient rubber body 1and terminate at the outer edge of the insert 2.

It is to be understood that the hard rubber insert 2 is to besemi-flexible so as not to interfere with the action of the heel orpresentsucli unyielding resistance as would cause it to wear through inthe same manner as a metallic washer. Moreover the resilient rubberportion and the hard rubber insert are vulcanized so as to form ineffect a solid rubber heel.

It is found-in practice that the heel of the present invention isstrong, simple, durable and inexpensive in construction as well asthoroughly elicient and practical in use.

The modified construction of heel shown in Figs. 4, 5 and 6 ispractically the same as that shown in the other figures of the drawing,the principal difference being that the central portion of the insert 2ais cut away, as indicated at 2b so as to allow the resilient rubber toflow through and thus form a solid cushion of resilient rubber for theheel proper. Moreover, in this case, the heel as a whole is renderedmoreA homogeneous. The insert in either form of the invention may bemade not only of hard rubber, but. also of any suitable fiber or othercomposition having the necessary strength. In the modified constructionthe nail holes 3b extend through the insert as well as the body portionof the heel.v This may be the case in the other form of heel if desired.

AIn testimony that I Claim the foregoing :is my or '1, I have heretoaiiixed my signature in the presence of two Witnesses.

FRANKLIN WILLIAM KREMER.

Vhut is claimed as new is A heel comprising a nail-holding insert oi'hard rubber and a soft rubber. body in which the insert is completelyinclosed, the insert and the body being vulcanized t0- gether, toprevent relative movement between the insert and the body. v
